What Did the Dodo Bird Eat? And How Do We Know?

The dodo (Raphus cucullatus) was a flightless bird, native to the island of Mauritius, which has become a widely recognized symbol of extinction. First encountered by Dutch sailors in 1598, this unique bird, related to pigeons and doves, quickly captured public interest due to its unusual appearance and fearless nature. Despite its fame, much about the dodo’s life, including its specific dietary habits, remained largely a subject of scientific inquiry for centuries following its disappearance around 1662.

The Dodo’s Diet

The dodo’s diet primarily consisted of the abundant plant life found on Mauritius, making it a frugivore. It consumed fallen fruits, seeds, nuts, bulbs, and roots from the forest floor. Specific examples of its food sources included palm fruit and likely the fruits of trees like the tambalacoque, also known as the dodo tree. The dodo’s large, robust beak was well-suited for handling and swallowing large fruits and other plant material.

While largely herbivorous, evidence suggests the dodo was an opportunistic omnivore, supplementing its diet with small invertebrates. It likely scavenged for readily available shellfish and crabs, particularly in coastal areas, which would have provided essential minerals and proteins. However, there is no evidence to suggest that dodos ate fish. A key adaptation in the dodo’s digestive system was the presence of gizzard stones, or gastroliths. These stones, retained in its muscular gizzard, helped break down tough, fibrous plant matter and extract nutrients.

Uncovering Dietary Secrets

Scientists have pieced together the dodo’s probable diet through various lines of evidence, given the impossibility of direct observation. Historical accounts from early European settlers and sailors provide some insights, though these are often limited and unreliable due to biases or embellishments. For instance, some early reports mentioned the dodo consuming fruits and seeds.

Fossilized remains have offered more concrete clues about the dodo’s dietary habits. The discovery of gizzard stones alongside dodo bones provides strong evidence of their role in grinding tough plant material. Analysis of the dodo’s bone morphology and ecological context also contributes to understanding its diet. Researchers have studied the types of plants and animals available in Mauritius’s pre-human ecosystem to infer the dodo’s food sources. Combining these historical, paleontological, and ecological approaches allows for reliable inferences about what the dodo consumed in its native habitat.
